Meet the Guy Behind the Palo Alto Tutorials
Palo Alto tags are much more powerful than just color-coding your security policies. In this video, I'll walk you through how tags can be used to organize, automate, and simplify your Palo Alto Networks configuration. 📘 WHAT YOU'LL LEARN - What tags are and when to use them - Applying tags to Addresses and Security Zones - Using tags inside Security Policies to simplify rulesets - How Dynamic Address Groups (DAGs) use tags for automation - Dynamic User Groups and tag-driven user identification - Using the API to register addresses and push tags dynamically 🌐 USEFUL LINKS - FREE NETSums Resources: https://netsums.com/resources - Join the community for FREE: https://netsums.com/join 🧪 TRY DNS SINKHOLE IN A LAB (SAFETY & NOTES) I strongly recommend testing all examples in a lab or non-production environment. Never run unknown or potentially malicious payloads on production systems. The domain used in the demo is handled as malicious by Palo Alto Networks — only query it from an isolated lab environment if you understand sinkhole/testing behavior. If you want to try yourself the feature dns sinkhole, you can use this domain that is considered from the Palo Alto Networks as malicious: 79fe3m5f4nx8c1.pmr.cc 💡 API EXAMPLES You can use this CURL command to generate a Palo Alto API Key for you: curl -H "Content-Type: application/x-www-form-urlencoded" -X POST https://MY_FIREWALL.EXAMPLE.COM/api/?type=keygen -d 'user=MY_USER&password=MY_PASSWORD' You can use this one to set a dynamic tag to an address: curl -k -X POST 'https://MY_FIREWALL.EXAMPLE.COM/api/?type=user-id&key=MY_GENERATED_KEY' --data-urlencode cmd@uid-register.xml Contents of uid-register.xml (substitute all parenthesis with angled brackets, the YouTube description field doesn't allow angled brackets): (uid-message) (type)update(type) (payload) (register) (entry ip="192.168.100.1" persistent="1") (tag) (member timeout="0")bad-ips(/member) (/tag) (/entry) (/register) (/payload) (/uid-message) 👍 LIKE, SHARE AND SUBSCRIBE FOR MORE If you find this tutorial helpful, don't forget to give it a thumbs up, share it with your colleagues, and subscribe to our channel for more in-depth tutorials on network security and technology best practices. 🔗 CONNECT WITH US If you have questions, suggestions, or any kind of feedback, please don't hesitate to comment below!
